As part of the upcoming 2002 Johannesburg Summit, the United Nations report "Global Challenge, Global Opportunity: Trends in Sustainable Development" was issued on August 13, 2002. The report, in part, tells that "if current patterns of development continue, nearly half of the world's people will suffer from water shortages within the next 25 years, the use of fossil fuels, along with greenhouse gas emissions, will grow, and the world's forests will continue to disappear."
